Abstract

Provided is a method for acquiring information of network resources connected to ports of network switches. The method includes the steps of: acquiring network resource information including IP address, MAC address, computer name, and workgroup name of the network resources in a network including one or more network switches and a plurality of network resources connected to the switches; acquiring information of the ports of the switches and MAC address information of the network resources connected to ports of the switches; and matching the port-based resource information on the basis of the acquired network resource information and the acquired MAC address information of the network resource information based on the ports of the switches.

1 . A method for acquiring information of network resources connected to ports of network switches in a network including one or more network switches and a plurality of network resources connected to the respective switches, the method comprising the steps of:
 acquiring port configuration information of the switches and information of network resources connected to the ports; and   checking which switch a specific network resource is connected to and which port of the switch the specific network source is connected to.   
   
   
       2 . The method of  claim 1 , wherein the step of acquiring the port configuration information of the switches comprises the steps of:
 accessing the network switches to acquire MAC address table information; and   checking information on a specific port of the network switch and information on MAC address connected to the specific port.   
   
   
       3 . The method of  claim 1 , wherein the port configuration information comprises inherent port information that identifies port identification index, network interface index allocated to port, network interface name, description, and alias of switch port. 
   
   
       4 . The method of  claim 1 , wherein the network resource information connected to the ports comprises inherent network identification information of the network resources, including inherent MAC address information, IP address information, and computer name information of the network resources connected to the ports. 
   
   
       5 . A method for acquiring information of network resources connected to ports of network switches, the method comprising the steps of:
 acquiring network resource information including IP address, MAC address, computer name, and workgroup name of the network resources in a network including one or more network switches and a plurality of network resources connected to the switches;   acquiring information of the ports of the switches and MAC address information of the network resources connected to ports of the switches; and   matching the port-based resource information on the basis of the acquired network resource information and the acquired MAC address information of the network resource information based on the ports of the switches.   
   
   
       6 . The method of  claim 5 , wherein in the step of acquiring the network resource information, when one or more agents for collecting network resource information are installed in each segment of the network, an IP list module acquires network resource information collected by the agents through communication with the agents, and outputs or stores the acquired network resource information. 
   
   
       7 . The method of  claim 5 , wherein in the step of acquiring the network resource information, when the network resource information is not acquired from the agents, or when the agents are not installed, an IP list module accesses a switch supporting layer3 (L3) or higher service or a gateway equipment of the network and obtains the network resource information by acquiring ARP table information, which is IP address of ARP table MAC address information matched with the corresponding IP address. 
   
   
       8 . The method of  claim 5 , wherein the step of acquiring the information of the ports of the switches and the MAC address information of the network resources comprises the steps of:
 acquiring the network interface information by accessing a switch based on the IP address and community (or password) information of the network switches;   acquiring the port configuration information in the MAC address tables of the respective switches; and   acquiring the port-based identification information of the switches by matching the port configuration information with the basic interface configuration information.   
   
   
       9 . The method of  claim 8 , wherein the step of acquiring the network interface information comprises the step of acquiring separate or integrated interface configuration information, including information on number of interface of the switches, interface index information, interface description information, interface name information, and interface alias information. 
   
   
       10 . The method of  claim 8 , wherein the step of acquiring the port configuration information comprises the step of acquiring information on port number used in the MAC address table of the switches, and information on interface index number connected to the corresponding port, after acquiring the basic interface configuration information. 
   
   
       11 . The method of  claim 5 , wherein in the step of acquiring the information of the ports of the switches and the MAC address information of the network resources, the port information and the port-based MAC address information are acquired from the switches by acquiring destination MAC address information for transmitting or filtering packets inputted to the switches, and port information of the switches for reaching the acquired MAC address, based on IP address information and community or password information of the switches. 
   
   
       12 . The method of  claim 5 , wherein in the step of matching the port-based resource information, when specific network resource information containing MAC address is acquired from IP list module at agents installed in each segment, or when the network resource information is acquired from L3 or higher switch or ARP table of a gateway, IP address of the network resource, computer name and workgroup name are searched and merged based on MAC address information acquired based on the switch ports and MAC address acquired from the IP list module, and the port-based network resource information of the switches is outputted or stored, the port-based network resource information including specific port, MAC address of the corresponding network resource, IP address, computer name, and workgroup name.
